The Bosch Rexroth R911335151 (MSK075E-0200-NN-M1-UP1-NNNN) is an IndraDyn S synchronous servomotor featuring a winding resistance of 1.24 ohms and a moment of inertia of 0.00613 kg·m². It has a motor size of 075 and a standard design with a shaft including a keyway. The unit provides a continuous torque at standstill of 23.0 Nm (100 K) and a maximum torque of 88.0 Nm, with continuous current at standstill rated at 11.2 A and maximum current at 45.9 A. It operates at up to 3,850 rpm, delivers a constant torque of 31.5 Nm at 15.3 A under surface cooling, and utilizes natural convection for cooling. The servomotor is equipped with a multiturn absolute optical encoder (Hiperface interface, 128 signal periods, 240° rotatable connector) and an electrically-released holding brake with 23 Nm torque. Protection features include an IP65 rating and a noise level below 75 dB. The device has a winding inductivity of 8,400 mH, an insulation value of 155, a total motor length of type E, a weight of 22.5 kg, and an operating temperature range from -20 to +80 °C.

Frequently Asked Questions

How does the Hiperface encoder interface in the MSK075E-0200-NN-M1-UP1-NNNN improve system feedback?

The Hiperface interface provides both analog and digital position signals, ensuring precise synchronization with the drive controller. This enhances motion accuracy and stability during high-speed operations.

Why is a shaft with keyway used in the MSK075E-0200-NN-M1-UP1-NNNN motor?

A keyway shaft ensures secure torque transmission between the motor and load. It minimizes slippage, maintaining alignment in demanding industrial applications.

How does the electrically released holding brake in the MSK075E-0200-NN-M1-UP1-NNNN benefit vertical axis control?

The brake safely holds the load when power is off, preventing uncontrolled movement. This feature is especially vital for vertical or suspended load systems.

What advantage does the “E” motor length offer in the MSK075E-0200-NN-M1-UP1-NNNN model?

The E-length design provides an optimized balance between torque output and compactness. It allows integration in systems with space limitations while maintaining performance.

Can the MSK075E-0200-NN-M1-UP1-NNNN be used with multi-axis control systems?

Yes, it is compatible with advanced multi-axis servo controllers. This enables coordinated motion across multiple machines in automation or robotics setups.
